| srestegosaurio (on tchncs.de) | Hello, I have a quick doubt: I want to add a BTRFS subvol to my system. I modified the disko coinfig in my flake, how should I apply those changes?

| guiniol | So. I wanted to create a couple of extra datasets in an existing ZFS pool without wiping everything. Is there a way to either get disko to not remove existing data (is this what the mount mode does? I couldn't find much about it in the docs) or to get disko to give me the commands it would run to create those datasets (which I would the run myself). | 21:05:48 |

So. I wanted to create a couple of extra datasets in an existing ZFS pool without wiping everything. Is there a way to either get disko to not remove existing data (is this what the mount mode does? I couldn't find much about it in the docs) or to get disko to give me the commands it would run to create those datasets (which I would the run myself). Last time i checked disko doesnt support repartitioning | 21:15:18 |
| guiniol | so getting the commands it would run is really the only thing I can do | 21:16:27 |
| guiniol | I found the --dry-run mode (I really should have run --help first...), so let's see what that gives me | 21:16:55 |
| magic_rb | Id suggest you learn to use ZFS | 21:17:30 |
| guiniol | so | 21:17:37 |
| guiniol | the thing is I have the options I want in the disk config file | 21:17:55 |
 lassulus | in theory we have support for update scripts | 21:18:02 |
| lassulus | like create should be idempotent | 21:18:13 |
| lassulus | but please have backups and proof read the created script :) | 21:18:26 |
| guiniol | and I wanted to create the datasets as disko would create them because at the very end, I will wipe the machine and reinstall everything from backups | 21:18:27 |
| magic_rb | Ah | 21:18:37 |
| magic_rb | Dry run then | 21:18:43 |
| guiniol | so I don't want to have an incompatible option somewhere taht would make the zfs receive fail | 21:18:59 |
| guiniol | so, I did try --dry-run but apparently my flake on its own is not enough. I create the system with nixos-anywhere and disko complains about You must set the option ‘boot.loader.grub.devices’ or 'boot.loader.grub.mirroredBoots' to make the system bootable. | 21:19:48 |
| guiniol | I think there was something about a bootable device in the help, so let me try that again | 21:20:13 |
| guiniol | alright, I think I have it | 21:34:14 |
| guiniol | and there are basically no options being added :D | 21:34:29 |
| guiniol | Alright, another question: I had to disable the zfs-mount service because the ZFS dataset are also being mounted by autogenerated systemd units. Did I do something wrong? I am using non-legacy mount type datasets. | 22:38:58 |
